Definitions
- the invention relates to a vibration-damped vehicle steering wheel according to the preamble of claim 1.
- Steering wheel torsional vibrations which are mostly triggered by the chassis, lead to unpleasant vibrations for the driver. It is known to dampen steering wheel torsional vibrations by means of a rigid additional weight on the steering wheel. However, the additional weight has a disadvantageous effect on other vibration states of the steering wheel.
- a steering wheel is known from DE 200 16 639 U1, in which a vibration-damping element is arranged between the steering wheel skeleton and the steering wheel rim cover.
- the rings or a continuous insert are preferably made of a vibration-damping material or composite material, which are arranged on the steering wheel rim skeleton and support the steering wheel rim shell.
- a steering wheel is known from EP 1 180 464 A2, in which a container is arranged within the steering wheel rim, in which a weight is arranged in the form of a solid body, which can move within certain limits in the container and which vibrates in this way counteracts the steering wheel.
- a skeleton construction for steering wheels is known from DE 39 27 383 A1, in which the steering wheel rim is partially filled with a fluid medium.
- the aim is to reduce the moment of inertia of the steering wheel.
- the steering wheel back vibration should be damped and overshoot should be avoided.
- Another damping effect is to be achieved by the friction between the fluid medium and the inner wall of the steering wheel rim.
- the disadvantage of these arrangements is that the solid body or the liquid in the steering wheel rim can move without damping apart from the friction on the container wall or on the wall of the skeleton construction, whereby the vibration damping is impaired.
- the invention has for its object to further improve vibration damping on the steering wheel.
- a vibration-damped vehicle steering wheel with a steering wheel skeleton and a steering wheel cover and with at least one container arranged inside the steering wheel, in which at least one movable body is arranged as a vibration damper, means for at least one end face of the body movable in the direction of its longitudinal axis and the associated front face of the container are provided according to the invention Vibration damping provided.
- a movable body cannot move unhindered in the direction of its longitudinal axis between the end faces of the container, but its movement is slowed down by means of vibration damping, i.e. the body carries out a damped vibration.
- a liquid is provided as the means for vibration damping.
- the type of damping can be adjusted via the weight of the moving body and the proportion of the liquid.
- the container is completely filled with liquid.
- the liquid can consist of one component, e.g. Water, oil or glycerin exist. However, it can also be composed of several components for setting a desired vibration damping.
- At least one constriction can be provided in the container for additional damping of the liquids.
- several constrictions of different sizes are provided.
- At least one spring element is provided as a means for damping vibrations.
- the spring elements can be made of metal, rubber or Plastic.
- Another embodiment has both at least one spring element and a liquid. In this way, the vibration damping can be set within wide limits.
- a compressible medium such as e.g. Gas.
- the containers are arranged in particular in the steering wheel rim, and are preferably provided in the foam covering of the steering wheel without a direct connection to the steering wheel skeleton, i.e. the containers are surrounded on all sides by foam, so they are not on the steering wheel skeleton.
- the container can, for example, be arranged at least partially within a U-shaped steering wheel skeleton. Furthermore, the container can have different cross sections. It can have a circular cross section or a cross section similar to the trapezoidal shape.
- the movable body can be mounted on its circumference in order to achieve a smooth movement. It is preferably mounted at least approximately in a punctiform manner, the bearing points in particular having curved bearing surfaces. It may be appropriate to provide negative pressure in the container for the vibration damper.
- FIG. 1 shows a longitudinal section through a section of a steering wheel with a movable body arranged in a container with liquid.
- FIG. 2 shows a longitudinal section through a section of a steering wheel with a movable body arranged in a container between springs;
- FIG. 3 shows a cross section through the steering wheel section along the section line III-III of FIG. 2;
- FIG. 4 shows a longitudinal section through a section of a steering wheel with a plurality of movable bodies arranged in a container
- Fig. 5 shows a longitudinal section through a section of a steering wheel with several containers.
- FIG. 6 shows the section according to FIG. 1 with container constrictions
- Fig. 7 shows a cross section through the steering wheel rim along the section line III - III of Figure 2 with a modified container cross-section compared to FIG. 3.
- a section of a steering wheel rim 1 is shown in section.
- a section of a steering wheel rim skeleton 2 and a steering wheel cover 3 can be seen.
- a container 4 is provided in the steering wheel cover 3, which is preferably arranged in the lower part of the steering wheel 1 when driving straight ahead, and is curved in accordance with the curvature of the steering wheel rim 1.
- the arrangement of the container 4 in the lower part of the steering wheel 1 is expedient if only one container is provided. When using two containers, it is advisable to arrange them opposite, ie in the lower part and the upper part of the steering wheel when driving straight ahead.
- the container 4 is when foaming the Steering wheel cover 3 foamed in or is used after foaming in an opening of the steering wheel cover.
- a movable body 5 Arranged in the container 4 is a movable body 5 which has the cross-sectional shape of the container, for example the circular shape, but which has a smaller diameter than the inside diameter of the container 4 to ensure mobility. Furthermore, the movable body and also its longitudinal axis A is also curved in accordance with the curvature of the container 4.
- the container 4 is completely filled with a liquid F, for example. filled with water so that the movable body 5 is surrounded on all sides by the liquid, the lower section 6 of the gap between the movable body 5 and the inner wall of the container 4 being smaller than the upper one because of the gravity acting on the movable body 5 Section 7 of the gap between the movable body 5 and the inner wall of the container 4th
- the movable body 5 When vibrations occur on the steering wheel, the movable body 5 can move in the direction of its longitudinal axis A. As a result of the liquid surrounding the movable body 5 and in particular as a result of the liquid located between the end faces 11, 12 and the container end faces 13, 14, however, its movement is damped.
- the type of damping is set via the weight of the movable body and the amount of liquid, i.e., also over the length of the container, and also via the gap between the movable body 5 and the inner wall of the container 4. Because of the improved damping properties of this system compared to a freely movable body, a smaller movable body can be selected so that the weight increase by the movable body is reduced.
- a container 8 is provided in the steering wheel casing 3, in which the movable body 5 is arranged between two springs 9, 10, which extend between the end faces 11, 12 and the associated container end faces 13, 14.
- the movable body 5 is curved in accordance with the curvature of the container 8 and the steering wheel rim 1.
- the movable body 5 is supported at points 15, which have curved bearing surfaces 16, in an almost punctiform manner, so that only slight frictional forces act and the movable body 5 is therefore easily movable in the direction of its longitudinal axis A.
- the springs 9, 10 dampen the movement of the movable body 5 in the direction of its longitudinal axis A in a manner similar to that Liquid in the embodiment of FIG. 1.
- the oscillation frequency of the movable body 5 is set via the spring strength and the mass of the movable body.
- Fig. 3 it can be seen that the container 5 in this embodiment is partly within the U-shaped steering wheel rim skeleton 2 and that three bearing points 15 are provided at an angular distance of 120 ° in the sectional plane shown. Also in the storage area shown on the right in FIG. 2 by the bearing point 15, three bearing points are provided.
- three movable bodies 17, 18, 19 are provided in a container, which may have the shape of container 4 or container 8. In the embodiment of the container 4, these are surrounded by liquid. In the embodiment of the container 8, the circumference of the container 8 is like the movable body 5 of FIGS. 2 and 3. This storage is not shown in FIG. 4. However, it is also possible that the container 8 is additionally filled with a liquid as in the embodiment in FIG. 1.
- the movable bodies 17, 18, 19 have different sizes and masses.
- a spring 20 is arranged between the container end face 13 and the movable body 17.
- a spring 21 or 22 is provided between the movable bodies 17, 18 or 18, 19. Furthermore, it can be seen that a spring 23 is arranged between the container end face 14 and the movable body 19.
- a plurality of containers 24, 25, 26 are provided, in each of which a movable body 27, 28, 29 is arranged. Like the embodiments in FIGS. 2-4, these can be mounted at points and / or arranged in a liquid.
- Springs are provided between each movable body and the associated end faces of the containers, which are shown schematically in FIG. 5 but are not identified in any more detail, since their arrangement corresponds to that shown in FIG. 2. 5, an even wider range of damping can be achieved than in the embodiment of FIG. 4, since in addition to moving bodies of different masses and springs of different spring constants, liquids of different viscosities can also be used, such as water, oil, glycerin or a mixture of these liquids.
- constrictions 30 to 33 are provided which extend in a ring from the inner wall of the container into the container 4.
- constrictions 30 and 33 are larger than constrictions 31 and 32.
- the container 34 has a cross section approximating the trapezoidal shape. Furthermore, it can be seen that the container 34 is partially arranged within the U-shaped steering wheel rim skeleton 2.
